About the Role

Were looking for a Senior Fullstack Developer to work on core platform domains that power critical business capabilities across the Application Platform and Authentication Platform.

The backend is primarily Java-based, while frontend development is done using React or Angular. This is a hands-on, backend-leaning full-stack role for engineers who can work independently, navigate ambiguity, and contribute to building scalable, secure, distributed systems.

Youll collaborate closely with platform, infrastructure, and product teams, playing a key role in evolving shared systems that are foundational to the organization.

What Youll Be Doing

• Design, build, and maintain backend-heavy full-stack systems using Java as the primary backend language

• Develop frontend components using React or Angular, collaborating closely with product and design teams

• Build and operate distributed systems with scalability, reliability, and fault tolerance in mind

• Design and maintain APIs (REST and/or GraphQL) consumed across multiple internal platforms

• Implement and maintain authentication and authorization mechanisms (JWT, OAuth2, SAML, role- or policy-based access)

• Deploy, operate, and debug production systems in cloud environments (AWS, Azure, or GCP)

• Write and maintain automated tests (unit and integration)

• Use logging, metrics, and observability tools to troubleshoot production issues

• Collaborate with platform, infrastructure, and product teams to evolve shared services and systems

What You Bring

Must-Haves

• 5+ years of professional experience as a Software Engineer, with a strong backend focus

• Strong experience developing backend systems with Java

• Experience with modern frontend frameworks such as React or Angular

• Proven experience designing and operating distributed systems

• Strong experience building and consuming REST and/or GraphQL APIs

• Solid understanding of authentication and authorization concepts (JWT, OAuth2, SAML, RBAC/ABAC)

• Experience working with SQL and NoSQL data stores

• Hands-on experience with cloud platforms (AWS, Azure, or GCP)

• Experience with containerized development using Docker

• Experience with logging, monitoring, and production debugging

• Strong written and spoken English communication skills

• Ability to work independently, bring structure to ambiguity, and collaborate effectively

Nice to Have

• Experience working on platform or shared-infrastructure teams

• Familiarity with search technologies such as OpenSearch or Elasticsearch

• Experience in regulated or security-sensitive environments (e.g., healthcare)

• SRE-adjacent exposure (on-call rotations, production readiness, SLO awareness)
